Historio
Around 1630, chlorine was recognized as a gas by the Belgian chemist and physician Jan Baptist van Helmont.

Elemental chlorine was first prepared and studied in 1774 by Swedish chemist Carl Wilhelm Scheele.

By 1810, the scientific consensus was that chlorine was actually a compound that contained oxygen.

In 1811, Sir Humphry Davy concluded the new gas was in fact a new element.

Aplikoj
Chlorine is used for producing safe drinking water.

It is also extensively used in the production of paper products, dyestuffs, textiles, petroleum products, medicines, antiseptics, insecticides, food, solvents, paints, plastics, and many other consumer products.

Chlorinated compounds are used mostly for sanitation, pulp bleaching, disinfectants, and textile processing.
Elemental chlorine at high concentrations is extremely dangerous and poisonous
